THREADING-EYE FOR SHUTTLES.

Specification of Letters Patent.

7 Patented Apr. 22, 19121.

Application filed September 24, 1918. Serial No. 255,425.

To all whom it may concern:

Be it known that I, JOHN C. SHAMBOW, a citizen of the United States, residing at Woonsocket, in the county of Providence and Stateof Rhode Island, have invented a new and useful Improvement in Threading- Eyes for Shuttles, of which the following is a specification.

This invention relates to certain new and useful improvements in threading eyes for shuttles, and the primary object thereof is to provide a threading eye which is formed or cast in two pieces, so as to enable the finishing of the pieces to be accomplished in an easier and quicker manner, as distinguished from the prior one-piece castings or formations which latter render it difiicult to have easy access to the parts to be finished, with .the resultant expenditure of a great deal of time and tedious labor.

A further object of the invention is to provide a threading eye in which a thread engaging pin adjacent the delivery eye is free to rotate so as to enable the thread, if subjected to unusual strain or stress, to not become easily broken.

The invention has for its still further objects to providemeans for easily assembling the parts or pieces, and to generally improve the construction of the eye, and further resides in the details of construction and combination of parts hereinafter more particularly referred to and described.

p In the drawings a Figure 1 is a top plan vlew of the invention applied to a shuttle, the latter shown in fragment.

other part.

Fi .2 is a side elevation on. the delivery eye, slde of the shuttle.

Fig. 3 is a sectionon line 3-3 of Fig. 1.

Fig. 4 is an inner side elevation of one of the parts.

Fig. 5 is an outer side elevation of the part of Fig. 4.

Fig. 6 is an lnner side elevation of the Fig. 7 s an outer side elevation of the part shown in Fig. 6, and

Fig. 8 is, a rear end elevation of the two parts in their assembled positions.

In proceeding in accordance with the present invention, a two-piece or two-part eye is provided, one part 1 being formed with a lip 2, engaging a piece of felt 3, so as to sustain the latter in engagement with the adjacent end wall ofpart 1, the lip and felt having V-notches 4 in their upper ends to provide a thread receiving passage. Part or member 1 is formed with a depending stud 5 engaging in aperture 6, provided therefor in the shuttle bottom, as depicted in Fig. 8, and further has a curved horn 7, and a depending finger 8, as depicted in Fig. 5. A pin 9 is secured to member 1 and extends across the space between finger 8 and the adjacent wall 10 at the rear end of member 1. On its inner side member 1 has shoulders 11 and 12 (Fig. 1) and a pin 13 cast integral with the member and extending in the space between the shoulders 11 and 12, a hole 14: being provided to one side of the pin 13. An inclined lip 15 which is curved as shown in Fig. 8 is provided on the inner side of member 1. This lip is originally cast fiat and after finishing of the parts, by the use of a file, and emery paper or other finishing tools, the lip is then curved into its completed form shown in the drawings. A concaved thread engaging platform or passage 16 is provided below the The other piece or member 18 is of considerably less width than the member 1 and has a base 19 of a length so as to be received between the shoulders 11 and 12 of Fig. 4:, and has a perforation 20 to receive pin 13 and an aperture 21 to register with aperture 14. Member 18 further has a shoulder 22 to engage the shoulder 28 formed on the member 1 so as to thereby hold the member 18 in its relation to the member 1. A lateral anchoring lug 24 is formed on the outer side of member 18 and the latter is also provided with a wide slot 25 into which lip 15 proj eots, the lip projecting only sufficiently into the slot so that the thread in being threaded into the eye will be passed around the free edges of the lip 15 and due to the latter forming a curved and inclined shed or roof, it will be apparent that the thread will be prevented from becoming accidentally disengaged from the eye. The lug 24: of member 18 engages in a cutout 26 provided therefor in the shuttle and this member further has an arm 27 the upper face of 28 of which slopes downwardly and inwardly as depicted in Figs. 3, 6, and 8. The arm 27 and the inner end of horn 7 are received in corresponding cut-outs provided therefor in the shuttle body. As shown in Fig. 1 arm 27 has an overhanging front end part 29, which overlies the horn 7 so as to prevent accidental upward movement of the thread from between the horn and the part 29.

It will be noted that the pin 9 has both upper and lower bearings in the adjacent part of member 1, consequently this pin can freely rotate if subjected to any unusual strain or stress by the thread engaging there over in the passage of the latter through the delivery eye.

Referring to Figs. 1 and 8 it will be seen that the member 18 has its inner side abutting the outer wall of the passage 15, consequently the joint 10 (Fig. 8) between members 1 and 18 occurs 01]? center of the passage 16 and the thread will thereby be caused to travel to one side of this joint, so that there is little likelihood of its entering the joint.

A screw 30 is employed to secure the two parts in their assembled position and to the shuttle body.

In operation the thread is placed on the horn 7 and then moved to ride down on the latter under end 29 and over lip 15 and then is drawn somewhat forwardly and again downwardly to pass under the finger 8 and to engage the pin 9 which latter extends across the delivery eye of the shuttle. The thread accordingly will then travel horizontal in the V-passage 1 along the felt, through the passage 16, and under the lip 15.

From the above it will be observed that the inner side of the member 1 including the horizontal platform or passage 16 is readily accessible for finishing purposes and likewise the member 18 can be easily finished separate from member 1, and the parts then assembled to form the complete eye. It will be obvious that where the parts are made in a single casting, it would be very diflicult and and tedious as well as time consuming to finish the interior structure of the eye due to the inaccessibility of the parts.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is- 1. In a shuttle, a sectional threading eye, one of the sections having a complete longi tudinal co ncaved threading passage, and the other section abutting the outer side of said passage so as to form a joint to one side of the transverse center of the passage.

v2. In a shuttle. a threading eye composed of two sections, one of the sections having a complete longitudinal thread passage and the other section abutting the outer side of said passa e so that the joint between the two sections occurs to one side of the transverse center of the passage.

3. In a shuttle, a threading eye composed of two sections, one of the sections having a longitudinal horizontal thread passage, spaced right angular shoulders on the outer side of said passage, the other section having a base of a length to be received between said shoulders, and means to restrict movement of said sections in a plane at right angles to the plane of the passage.

4. In a shuttle, a threading eye composed of two sections, one of the sections having a pair of spaced vertical shoulders and a horizontal shoulder, the other section being formed to be received between the vertical shoulders and to engage the horizontal shoulder, and thread engaging means formed on the respective inner sides of the two sections. V

5. In athreading eye for shuttles, an eye member having a thread receiving 0 ening leading to the delivery eye of the s uttle, and a vertically disposed pin traversing said opening and having'upper and lower bearings to enable the pin to freely rotate.

6. In a shuttle, a threading eye includin a section having a side and a horizontfi platform projecting out from the side and formed with a complete threading passage, the outer side of said platform having spaced end shoulders, and a removable section formed to abut the outer side of the platform and to engage in the space between and with said end shoulders. V

7. In a shuttle, a sectional threading eye, one of the sections having a relatively wide base and a side, a complete securing stud depending from said base, said base being formed with a complete threading passage, and the other section forming the other side of the eye and a continuation of the adjacent side of the threading passage and being completely removable from the first named section to expose the entire inner face of the side of the same.

8. In a shuttle, a sectional threading eye, one of the sections having spaced end shoulders and a horizontal shoulder, the other section having a depending part received in the space between the end shoulders and formed with ends engaging the end shoulders and a portion seating on the horizontal shoulder.

9. In a shuttle, a threading eye formed in sections, an inclined lip of curved cross section formed on the inner face of one section and being arranged between the ends of said section, the other sectiong being removable and having a slot between its ends into which the lip projects.

10. In a shuttle, a sectional threading eye,

one of the sections having spaced abutments name to this specification in the presence of on 1ts inner slde and the other sectlon being two subscrlblng witnesses,
